For the uninitiated, fatbergs (which get their names from a portmanteau of "fat" and "icebergs") are giant, solid blobs of congealed fat, oil, grease, wet wipes, and sanitary products. They form in sewers when people dump cooking byproducts down drains, or in oceans when ships release waste products like palm oil. These sticky substances combine with floating litter to form what could be described as garbage heaps on steroids.

Fatbergs wash up on beaches, muck up city infrastructures, and are sometimes even removed with cranes from sewer pipes as a last resort. Few—if any—fatbergs, however, appear to be as potentially lethal as the one workers recently discovered under London's Whitechapel neighborhood. In a news release, private utility company Thames Water described the toxic mass as "one of the largest ever found, with the extreme rock-solid mass of wet wipes, nappies, fat and oil weighing the same as 11 double-decker buses."

Ick factor aside, the Whitechapel fatberg currently blocks a stretch of Victorian sewer more than twice the length of two fields from London's Wembley Stadium. Engineers with jet hoses are working seven days a week to break up the fatberg before sucking it out with tankers. But even with high-pressure streams, the job is still akin to "trying to break up concrete," says Matt Rimmer, Thames Water's head of waste networks.

The project is slated to end in October. But instead of simply disposing of the Whitechapel fatberg, officials want to make use of it. Argent Energy—which has in the past relied on sources like rancid mayonnaise and old soup stock—plans to process fatberg sludge into more than 2600 gallons of biodiesel, creating "enough environmentally friendly energy to power 350 double-decker Routemaster buses for a day," according to Thames Water.

"Even though they are our worst enemy, and we want them dead completely, bringing fatbergs back to life when we do find them in the form of biodiesel is a far better solution for everyone," said company official Alex Saunders.

In addition to powering buses, the Whitechapel fatberg may also become an unlikely cultural touchstone: The Museum of London is working with Thames Water to acquire a chunk of the fatberg, according to BBC News. The waste exhibit will represent just one of the many challenges facing cities, and remind visitors that they are ultimately responsible for the fatberg phenomenon.

"When it comes to preventing fatbergs, everyone has a role to play," Rimmer says. "Yes, a lot of the fat comes from food outlets, but the wipes and sanitary items are far more likely to be from domestic properties. The sewers are not an abyss for household rubbish."

This Smart Accessory Converts Your Instant Pot Into an Air Fryer

If you can make a recipe in a slow cooker, Dutch oven, or rice cooker, you can likely adapt it for an Instant Pot. Now, this all-in-one cooker can be converted into an air fryer with one handy accessory.

The internet can transport you to the most famous theme park rides on Earth, like Pirates of the Caribbean and Space Mountain in Disney World. It can also introduce you to obscure attractions you may have trouble believing exist in real life. If you're interested in the stranger side of theme parks, it doesn't get much weirder than Hundeprutterutchebane in Denmark, a.k.a. the dog fart rollercoaster.

Hundeprutterutchebane is one of the more memorable attractions at the Danish amusement park BonBon-Land. While it's not the most intense rollercoaster, it may leave riders feeling nauseated by the end. After boarding cars shaped like a character called Henry the Farting Dog, they zoom past another sculpture of Henry lifting his leg over a pile of poop. The coaster also passes through a tunnel filled with sounds of canine flatulence. You can experience the unique ride in the video below from Theme Park Crazy.

Hundeprutterutchebane isn't the only attraction at BonBon-Land that appeals to an immature sense of humor. There's also a "skid mark" coaster and a "horse dropping" ride, as well as pictures of urinating, defecating, and vomiting cartoon animals throughout the park. Even though it's themed around gross-out humor, BonBon-Land was actually started by a candy company. BonBon specialized in selling candies with cheeky names like "pee diapers," "seagull droppings," and "dog fart."
